From: "David A. Long" <dave.long@linaro.org>
This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding hooks into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing.
The following changes have been made for v2:
1) The last dependencies of uprobes on kprobes have been removed and the two features may now be independently configured. 2) The larger changes have been separated into a few stages. 3) Use of "void *" has been replaced with an appropriate pointer type in various places. 4) The arm kprobes-test module has been changed to work better with a thumb-mode kernel.
These patches are based on v3.12-rc5.
David A. Long (11): uprobes: move function declarations out of arch uprobes: allow ignoring of probe hits uprobes: allow arch access to xol slot ARM: move shared uprobe/kprobe definitions into new include file ARM: move generic thumb instruction parsing code to new files for use by other features ARM: use a function table for determining instruction interpreter actions ARM: Disable jprobe selftests in thumb kernels kprobes: Remove uneeded kernel dependency on struct arch_specific_insn ARM: Finish renaming ARM kprobes APIs for sharing with uprobes ARM: add uprobes support ARM: Remove uprobes dependency on kprobes
Rabin Vincent (2): uprobes: allow arch-specific initialization uprobes: add arch write opcode hook
